How about we just figure out how to not kill this planet first?

Nope. And, I'm sure there are plenty of people who will say that it would make the whole economic system collapse. Of course, we'd also have to raise the wages of everyone below the poverty line by an equal percentage and tax the rich at a reasonable rate and get this all passed through a congress that is entirely made-up of millionaire corporate whores, but when the dust settles, we'd all be better off.

Once again with the, "Here you go immigrant: turn this shit into gold with the magic of your superhuman resourcefulness." I used to work in refugee resettlement. Here's the thing about our immigration policies that no one wants to talk about: immigration policies, low minimum wage, and criminalization of poverty are what maintains the wage slave class in this country on which the wealthy have always relied. Our funneling of resources to the wealthy, low wages, and drug use to medicate our frustration and pain create a vortex of desperation that pushes people out of their homes in places like Mexico, Central and South America and encourages them to be drawn north on the gamble of finding prosperity in jobs at pay rates that most Americans will not work for. If we forgave or even restructured loans to those countries, tied the federal minimum wage to housing costs, de-criminalized drugs, and put a lot more into treatment and education, immigration would not be such a "problem". Also, when a certain party finally realizes that its shrinking demographic of voters needs to be more diverse and they stop being so blatantly anti-immigrant and racist, most immigrants will switch parties because most are religious and socially conservative, which will severely hurt the other party in many states and cities. Immigration is neither the fix for every problem nor the source of every problem.
